Brain birth

You’ve probably heard of neuroplastity, right? Neuroplasticity is the ability of the brain to change and reorganise itself throughout our life. Our brain literally changes itself to enable you and me to become better and more efficient at skills we practice. Brain circuits that we use regularly not only ‘wire together’ but, due to a process called myelination, can transmit information up to 100 times faster than standard brain circuits. If you’re not very good at knitting or sudoku or maths or telling jokes, it’s because you haven’t given your brain enough opportunity to adapt. Neuroplasticity is also the process that allows people like Jodie Miller to have half of her brain surgically removed and to recover to live a relatively normal life.

But, do you know about neurogenesis? It was only a few years ago that psychology and biology textbooks were stating that the adult human brain has approximately 100 billion brain cells and you can’t grow any more. Wrong. It turns out that mammals – like us – are constantly growing new brain cells;  particularly in the hippocampus, an area associated with memory and learning.

Ultimately, it is the mechanics of neuroplasticity and neurogenesis that allow us to learn.

It’s also why the phrase: “I’m just not good at _________” doesn’t really make sense scientifically. Instead, we should encourage the phrase: “I’m just not good at _________ yet“. Those three simple letters, y-e-t, encapsulate an understanding of the incredible ability of the human brain to help us become better at whatever we choose to practice.
